Product Summary

The PCA9635PW is an I2C-bus controlled 16-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. The PCA9635PW is one of the first LED controller devices in a new Fast-mode Plus (Fm+) family. Applications of the PCA9635PW include: RGB or RGBA LED drivers, LED status information, LED displays, LCD backlights and Keypad backlights for cellular phones or handheld devices.

Parametrics

PCA9635PW limiting values: (1) supply voltage VDD: -0.5 to +6.0V; (2) voltage on an input/output pin VI/O: Vss -0.5 to 5.5V; (3) output current on pin LEDn IO (LEDn) : 25mA; (4) ground supply current Iss: 400mA; (5) total power dissipation Ptot: 400mW; (6) storage temperature Tstg: -65 to +150° C ; (7) ambient temperature Tamb: -40 to +85° C.

Features

PCA9635PW features: (1) 16 LED drivers; (2) 1 MHz Fast-mode Plus compatible I2C-bus interface with 30 mA high drive capability on SDA output for driving high capacitive buses; (3) 256-step (8-bit) linear programmable brightness per LED output varying from fully off (default) to maximum brightness using a 97 kHz PWM signal; (4) 256-step (8-bit) linear programmable brightness per LED output varying from fully off (default) to maximum brightness using a 97 kHz PWM signal; (6) Sixteen totem-pole outputs (sink 25 mA and source 10 mA at 5 V) with software programmable open-drain LED outputs selection (default at totem-pole). No input function; (7) 25 MHz internal oscillator requires no external components; (8) Edge rate control on outputs; (9) ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101; (10) -40°C to +85 °C operation; (11) Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA; (12) Packages offered: TSSOP28.
